*** Data Archive files
** This data archive contains files in STATA format necessary for replication of our Review of Economics and Statistics paper. Estimation was carried out in Stata 10.0

* There are two data files:
- ReStatDataFile.dta - this contains data on the lottery winners and losers in Tonga, and is used with the do file Tables1and4to10.do to carry out the estimations in Table 1, and in panels A and B of Tables 4 to 10. It is also used with Table11.do to carry out the multiple hypothesis testing.
- ReStatDataFile2.dta - this also contains data on non-applicants to the lottery, and is used with the do file Tables2and3.do to look at selection into the lottery in Tables 2 and 3, and to carry out panel C of Tables 4 to 10. 

In addition the do file TFLSfile.do gives the code needed to calculate non-experimental estimates using the Tongan Labor Force Survey and HIES data. However, users need to request access to this data from the Government of Tonga.
